From The Esoteric Tradition by G. de Purucker

The Esoteric Philosophy rejects as philosophically untenable the notion prevailing in the Western world that chance or fortuity is the cause of either circumstances or environment, or of the directing impulses which beings have and follow while living in their environment. For a universe which contains chance or blind fortuity in any degree must be a universe which is lawless, and based on neither reason nor mind. What men popularly call chance is merely what knowledge or research has not yet brought sufficiently to light as being a link in the chain of universal causation.
Nature, or the universal cosmos, is an organism, built of innumerable minor beings and entities and things which individually are each one likewise an organism. Thus, nature may be viewed as an incomprehensibly great cosmic web, into which everything that is is woven, because forming a component part of the cosmic whole. Man, as an individual minor organism, is throughout eternity interwoven with the environing cosmic strands of the great web of life. Every thought he has, every emotion he experiences, and every action consequent upon the impulses arising from these thoughts and emotions is thus forming a most intricate web of destiny which man is constantly weaving around himself and which, in very truth, is from one point of view himself.
But this is not fatalism, which says that man is the mere puppet or will-less victim of an inscrutable destiny which tosses him hither and yon, whether he will or whether he nill. On the contrary, the teaching of the Esoteric Tradition is that man is a willing agent throughout his beginningless and endless course of destiny. He constantly exercises his modicum of free will, which will is free in proportion with the degree which he has attained in rising toward self-conscious reunion with his monad, the Self of his many human selves manifesting as reimbodiments in the spheres through which he passes.
